SIGHT-FEED DEVICE.

and State of Illinois, have invented certain new and useful Improvements in Sight-Feed Devices, of which the following is a specification.

My invention is an improvement insight it feed devices, and has for its object to provide a device of the character specified adapted for use with internal combustion engines, to feed water to the manifold, wherein the amount of water fed is under observation, and can be easily regulated to the required amount.

In the drawings:

Figure l is a side view of a motor provided with the improved-feed;

Fig. 2 is a vertical section, through the feed;

Fig. 3 is an end view.

The present embodiment of the invention is shown in connection with the motor 1 of a motor vehicle indicated at 2, the said motor bein an internal combustion engine, and the lntake manifold 3 of the motor is connected by a pipe 4 with the sight feed, the said feed also being connected by a pipe 5 with the connection 6 from the water circulation system of the motor to the radiator, indicated at 7.

, The sight feed comprises a casing consistin of a hody 8 and branches 9 and 9, which extend snhstantially parallel with each other from the hody. The body has threaded recesses 10 and ii into which are threaded nipples 12 and 13, and the said nipples are connect e the pipes at and 5 heiore mentioned.

The branch 9 of the casing 8-9' -9 has a recess it, and this recess communicates by a port 15 with the recess 10 heifers mentioned. llhe branch of the casing has a recess 16 which connnunicates hy a passage oin this recess downwardly, delivering the recess i lin branch 9. noticed the loranch 9* has is forming extension of the .8, the in or end of is nipple top of the hranch 9, hut spaced enough so that the feed through nipple he see The passages 15 and a co v needle valves and Y have threaded err- Specification of Letters Patent.

, gagement with openings in the branches 9 In operation, the water feeds from the connection G-through the pipe 5, the nipple 13 into the passage or recess 11 of the casing, from whence it flows by way of the passage 18 to the recess 14:. From here the water flows by way of the passage 15 to the pipe 4 and to the intake manifold. lhe flow of the water may be nicely regulated by means of the two valves, and when once regulated the feed is in sight, so that the driver has the feed always under observation. The casing 8-99* is arranged on the dashboard 22 of the vehicle, as shown in Fig. i, in conwenient position for the drivers observation.

After the device is once set to the proper feed it is not necessary to change the same. When the circulating pump of the motor is working there will be a constant circulation of water, but this circulation will stop when the pump stops, that is, when the motor stops.

The improved device is also adapted for use as a primer. ()n cold mornings, when the motor usually starts with diflicnlty, the sight feed can be used to squirt a little gasolene into the cut or bowl. From there it will flow into the manifold and when the,

motor is turned it will start. This is especially adapted for cars the Ford class, which do not have prim As illus rated in a, the er end of the howl 14% is entirely open and entirely unobstructed so that a quantity of riniing fluid may he readily introduced the howl. for subsequent introduction into the intake manifold.

that the created by the operation of the ere.- draw uantity to tne pine into the pipe 4 from the bowl 14. The needle valve 20 may of course be regulated for controlling the quantity of air supplied.

Should it be desired to admit wateronly to the'pipe 4, the upper needle valve 21 may be unseated so as to cause a quantity of water to pass through the branch 9" and enter the bowl 14 until the water level extends above the lower valve seat. Therefore, the discharge passage 15 will be below the water level and no air will be permitted to enter the passage.

Should it be desired-to supply only a priming fluid to the pipe 4 and consequently the intake manifold, the upper needle valve 21 is closed and the lower needle valve is opened so that when a quantity of riming fluid is introduced into the bowl 14, t e same will flow through the passage 15 and the pipe 4.

I claim:

1. In a sight feed device, the combination with a body provided with upper and lower spaced branches having valve seats, upper and lower needle valves threaded longitudinally into said branches and engaging the valve seats of the same, said body being provided with inlet means in communication with said upper branch and with discharge means'in communication with said lower branch, said lower branch being provided with an open bowl extending below said lower needle valve and the valve seat of the same, the space between said upper and lower branches being entirely unobstructed to permit apriming fluid to be in-' troduced into said bowl.

2. In a sight feed device, the combination with a body rovided with upper and lower spaced branc es having valve seats, upper and lower independently adjustable needle valves threaded into said branches and engaging the valve seat of the same, said lower branch being provided with anopen bowl extending below said lower needle valve and the valve seat of the same, the space between said upper and lower branches being entirely unobstructed to permit a priming fluid to be introduced into said bowl.

3. The construction set forth in claim 2, said upper branch being provided with a depending nipple directly above and in spaced relation to said bowl.
